To all whom it may concern:

,Be it-known that we, FRANK M. PETERS andHnNRY H. HUNGERFORD, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Wrapping Packages, of which the following is a specification. This invention relates to machines for applying to pasteboard and other boxes, packages, or cartons an outer wrapper of paper or like flexible material.

One object of the invent-ion is to provide an improved automatic mechanism whereby boxes, cartons, or other packages may bewrapped, with a minimum of manual labor and at a-rapid rate, thus insuring a reduction in the cost of these operations and in the cost of the package.

A further and more specific object of the invention is to provide a mechanism wherein the folding of the wrapper around the package may be performed with a minimum of moving parts of. the machine, a distinctive feature of. the present machine bein the provision to a considerable extent of stationary folding means provided with parts that serve to produce and lay in proper orderi-theend folds of the package.

To these andother ends the invention con sists'in certain novel features which we will now proceed to describe, and will then more particularly pointout in the claims.

Our invention will be readily understood when considered in connection with the accompanying drawings, which illustrate the best mechanical embodiment thereof which we have as yet devised, and in which Figure 1 is an end elevational view of the receiving end of the machine; Fig. 2 is a similar view of the discharging-end of the machine; Fig. 3 is a side elevational view; Fig. at is a view of the opposite side, partially broken. away at the ends; Fig. 5 is avertical sectional view longitudinally of the machine; Fig. 6 is an enlarged vertical sectionalyiew longitudinally of the package and paper feeding mechanisms and the wrapping chute; Fig. 7 "is a similar view to F ig. 6, in a diiferent vertical plane and showing the mechanism from the opposite side; Fig. 8 is a vertical transverse section vin the plane of the wrapping chute, looking toward the discharge end of the machine; Fig. 9 is a transverse sectional view in the Specification of Letters Patent.

taken on a lower plane; Fig. 22 is an end view of a wrapped package, illustrating the end formation of the folded wrapper; Fig. is a side elevational view of the niechanism employed for applying a strip of paste to one longitudinal edge of the wrapper; and Figs. 24 and 25 are vertical sectional views, viewed from opposite sides, through the pasting trough shown in Fig. 23 and more particularly illustrating the construction of the jointed lever carrying the pasting roller. Y

Before proceeding to a detailed description of the various parts and mechanisms of the machine as disclosed in the drawings, we will briefly outline in a general way the principal features of the machine and its mode of operation. The machine is of that general type which employs a vertical package chute with a package-depressing plunoperatingtherein, means for delivering the packages successively into the upperpart of said chute, and means for delivering a wrapper across the path of each package preliminary to its depression by the plunger. Horizontal plates reciprocating across the chute above each package serve to. form the top longitudinal folds of the wrapper; while devices located in the opposite. ends of the chute, and constituting the principal novel elements of our present machine serve to effect the end folds of the wrapper. The top end fold is created by means of a rotating shoe that is caused to wipe downwardly over the upper portion of the end of the package; while the two lateral end folds and the bottom end fold are created by means of a folder of special formation held substantially stationary except for a slight resilient yielding capability to enable it to adjust itself to "the end of the package as the latter passes thereover. From the bottom of the package chute, at which point the wrapper has been fully applied and folded, the package is advanced horizontally into the field of actioil of thesealingmechanism located opposite each end, where a pair of seal-carriers traveling horizontally toward and from the sides of the machine operate to withdraw from a suitable box or holder labels or other seals, and, submitting the latter to an application of paste while travelingtoward the ends of the package, apply suchseals or labels to the latter in succession, whence the wrapped and sealed packages are withlrawn from the machine and discharged by a suitable conveying mechanism which engages the packages at their ends for a sufficient interval of time to enable the seals to fully adhere to the ends of the wrapper packages.

In the drawings, the main frame, whichsupports the various mechanisms of which the apparatus is composed, is shown as constructed essentially of a pair of parallel vertical side-frame members 1 and 2, suitably connected and rigidly spaced. Journaled in and between the lower portions of said side frames at the discharging end of the machine is the main driving shaft of the apparatus, designated by 3, to which power is supplied through a suitable clutchcontrolled pulley t (Fig. 2). On the end of said shaft overhanging the side-frame 1 is a pinion 5, which meshes with and drives a gear 6 on a superposedtransverse shaft 7 (Fig. 2). The gear 6 in turn meshes with and drives a gear 8 on a su gierposcd transverse shaft 9, which latter shaft carries, outside the gear 8, a smaller gear 10 meshing with and driving a gear 11 on an upper shaft 12 journaled in and transversely of the side-frame members 1 and 2. From the several transverse shafts 3, 7, 9 and 12, power is taken through connections hereinafter described for actuating the various movable elements of the several mechanisms.

At the upper portion of the receiving end of the machine is located the package fer-d mechanism; and immediately beneath the same the wrapper feed mechanism. The package feed is substantially identical with that disclosed in Letters Patent No. 790,454 granted to us on the 23rd day of May, 1905, to which reference may be had for a complete description thereof. This mechanism, which is most fully shown'in Figs. 5', 0 and 7, comprises as its principal elements a horizontal chute 13 alongwhich the packages are fed in sidewise juxtaposition, the delivery of the packages into the chute being effected by a follower--14, and controlled by lateral stopfingers 15 and an overhanging stop-finger 16. The follower 14: is recipro cated by means of an oscillating pinion 17 engaging a rack 18 (Fig. on its under side, the shaft 19 on which the pinion 17 is mounted being actuated on one side of the machine by the means shown in Fig. 3, wherein 20 is a pinion on the end of shaft 19 engaged by a sector gear 21 thatis oscillated by a connecting r'ed 22 at its rear end straddling the shaft 12 and having a roller 23 playing in a cam-groove 24 formed in the inner face of the cam 25 fast on shaft 12. I The lateral stop-fingers 15 are mounted on horizontal shafts 26 that are oscillated by means connected with the follower 1}, such means being fully disclosed in the Patent No. 790,4t5st, above referred to. The overhanging stop-finger 16 is normally drawn downwardly by a spring 27 (Fig. 7), and is raised at the proper intervals toJpermit the advance of the foremost package by means of an inclined shoe 28 moving beneath a roller 20 on the lower end of an arm 30 connected to the shaft 31 on which said finger is mounted.

The wrapper feed mecl'ianism herein .shown, which directly underlies the package feed mechanism above described is identical with that shown and described in our Let ters Patent No. 7 02,67 3, granted to us Juhe 17, 1002, to which reference may be had for a complete description thereof. The principal features of this mechanism consist of the following. 32 (Fig. 1) is a table or platform mounted on the upper end of the screwthreaded rod33 supported in a vertical bearing 3 1 and provided with an actuating ratchet ring 35 on its lower end. This latter is given a slow intermittent rotation by means of a pawl 30 carried on one arm of the bell-crank lever 37 (Fig. 12), the other arm of which is connected by a link 38 with an arm 30 pivoted at 4.0 to a. cross-member of the frame, said arm 3.0 being given a slight oscillation by means of a link 11 piv oted thereto at one end and at its other end encircling an, eccentricon a longitudinal ro' tary sh aft42 that constitutes an extension of y a centrally disposed longitudinal shaft 43 that is geared to and driven from the shaft 7
